Clematis and tomatoes are two exceptions to the usual rule, and are best planted 6 inches deeper than the soil level in the pot. This protects the stem bases from mechanical damage, and helps prevent clematis wilt, whose fungus enters where there's damage. It also helps keep the roots cool.

UPDATE: as of June 2010 my clematis is still going strong. She survived the blizzards this past winter just fine. Actually I layered her and now have two plants side by side. I have lost track of how many vines I have. The longest ones are maybe 5-6'. She bloomed for a solid 6 weeks from the beginning of May until mid/late June.
